<i><b>Aim</b>: to assess the retina (including peripapillary retinal nerve fiber layer/RNFL and retinal vessel diameter) in patients with tuberculosis (TB) or HIV/TB coinfection in the lack of abnormalities detected by standard eye exam using optical coherence tomography (OCT).</i>
</p>
<p>
<i><b>Patients and Methods:</b> all patients were divided into three groups. Group 1 (n=19) included patients with HIV/TB coinfection. Group 2 (n=18) included patients with pulmonary and extrapulmonary TB. Group 3 (n=20) included healthy volunteers (controls). All patients underwent standard eye exam and OCT (iVue-100 v3.2, Optovue, USA) to measure peripapillary RNFL thickness, central macular thickness, and the first-order retinal vessel diameter (eight vessels).</i>
</p>
<p>
<i><b>Results</b>: OCT demonstrated greater peripapillary RNFL thickness in the nasal sector (by 13.4–18.3%) and central macular thickness (by 4.0–7.5%), narrowing of retinal arteries, and enlargement of veins (predominantly temporal). These patterns may illustrate retinal microcirculation in the setting of a pathological condition (HIV/TB, including highly active antiretroviral therapy [HAART]) and be a harbinger of further abnormalities of ocular structures and central nervous system.</i>
</p>
<p>
<i><b>Conclusion</b>: OCT identifies changes in vessel diameter, central macular thickness, and peripapillary RFNL thickness before visual disturbances in preclinical eye changes in patients with HIV/TB coinfection.</i>
